welcome to bbc news, broadcasting to viewers in north america and around the globe. i'm reged ahmad. our top stories: a stark warning about climate change. as a key un summit opens, experts say the threat posed by rising temperatures has never been worse. after some of the worst riots in paris for decades, president macron‘s government promises tough action against anyone who resorted to violence. a ceasefire in the trade war between the us and china. donald trump and xijinping put punishing tariffs on hold — for now. and down on one knee, then down the drain. new york police reunite the couple with their engagement ring that fell down a grate in times square. hello and welcome.

this year is going to be one of the four hottest on record. that's the warning from the united nations climate chief, patricia espinosa, who was speaking in poland at the start of an international conference on tackling climate change. she says global warming is posing a greater threat to humanity than ever before and called for everyone to grasp the reality of the situation. the effects that are happening are being — are affecting communities around the world, casualties, destruction in so many places, suffering, a lot of suffering derived from the consequences of climate change, just make it — really make our work more urgent. well, a very strong message there from the united nations, but it seems it isn't necessarily getting through. cutting back on the use of fossil fuels like oil and coal is seen as vital if we want to reduce emissions which contribute to climate change.

but in poland — the host for this summit — that's just not happening. our science editor david shukman reports. a mountain of coal lies freshly dug at a mine, one of many here in southern poland at the centre of arguments over what to do about global warming. ok, so we're on our way down. and i'm starting to feel the air pressure on my ears now. we arrive in an underworld, nearly one kilometre down. our first sight of the mining process. this coal is used to make steel, but most is burned to generate electricity. we're led through a series of long, dark tunnels, picking our way very carefully. we reach a tangle of cables and pipes, and the rock above us keeps shifting. that sound of rock cascading comes with the odd very loud crack. it's incredibly unsettling.

we're told, don't worry, it's just the rock working, as they call it. this is literally the coal face, and despite that spray of water, it's amazingly dusty down here, and very noisy. a really hostile place to work, and because coal can be so polluting, many countries, including britain, have moved away from it, but here in poland, thousands of people work in the coal mines. coal is a mainstay of the polish economy. so while climate scientists say the world should move away from coal, here, it looks set to last for decades. the miners are worried because the un climate conference is discussing a future without coal. but back at the surface, one green campaigner offers

a different vision, of clean solar power. he knows he's outnumbered here. burning coal, burning fossilfuels, using fossil fuels in the energy sector, it is a source of huge co2 emissions, and it hurts our climate, it hurts our planet. this region has some of the dirtiest air in europe, something that'll focus minds as the climate talks get under way. david shukman, bbc news, in poland. the french president emmanuel macron has held emergency talks, following some of the worst rioting in paris in recent years. police say they arrested more than 400 people and more than 100 were injured, after protests against high fuel taxes and rising prices erupted into violence. from paris, lucy williamson reports. france's scars are visible today, burnt into its most exclusive streets. the cost of economic conflict, long felt outside the city centres,

now being scrubbed inch—by—inch from the capital's face. last night's violence showed this movement changing, anarchists and agitators nowjoining in. but even some peaceful protesters say france's institutions are not working and rebellion is overdue. mr macron met his government for a crisis meeting today. one option on the table — a state of emergency. the president was booed as he arrived to thank the firemen on duty for the protest. fresh from the battles of the 620 summit in argentina, he's facing even tougher diplomacy at home. the most popular demand at protest sites around the country — macron resign. they're cleaning off the graffiti now, but the discontent that sparked this movement is harder to wipe away.

president macron has cast himself as an economic reformer, who stands firm against protestors, but when do protestors become simply the french people? jean will be 70 this month, but he was at the protest here last night too. translation: if the protest had gone very calmly, macron would have come back from argentina and said "it's all fine, it'll die down, i'll stick to my position and i won't change anything." it's sad to say, but it's the reality. among the targets last night was yasmin‘s car. she's not a government representative, but a single parent, with five children. translation: i understand the protestors, but the way they are acting right now, no. we are not dying from hunger, we have social care. it's not perfect, but i also work and raise my kids, i suffer from the tax rises too. mr macron built his presidency on a divided opposition. this new movement is united for now,

led by social media, not by politicians. how much will it damage the man who leads france? lucy williamson, bbc news, paris. the saudi—led coalition in yemen says a united nations plane is to fly into the capital, sanaa, on monday to evacuate injured houthi rebels. 50 wounded militants will be flown out to oman for treatment in what the coalition is calling a "confidence building" measure, ahead of planned peace talks in sweden this week. world leaders continue to press for an end to the four—year conflict, that has pushed yemen to the brink of famine. in regional elections in southern spain, a far—right party has won seats for the first time since military rule under general franco. in a resurgence of nationalism that has marked elections in other parts of europe, the vox party won 12 seats in andalusia — making it a potential kingmaker in any future right—wing coalition. the governing socialist party gained more seats than any other party,

but with a reduced majority. fears of an all—out trade war between the united states and china have receded after a meeting between donald trump and the chinese president xijingping at the g20 summit in argentina. in a temporary truce, the us has suspended plans to increase tariffs on chinese goods, and beijing has agreed to buy more american products. our north america editor jon sopel‘s report contains some flashing images. president trump arrived back into washington early this morning, looking tired, but buoyed by what he said was an incredible deal with china. he and president xi met for 2.5 hours at the g20. president trump sounding optimistic there could be a breakthrough, in the escalating trade war between these two economic superpowers. the relationship is very special, the relationship that i have

with president xi, and i think that is going to be a very primary reason why we'll probably end up getting something that will be good for china and good for the united states. an increase on tariffs will be put on hold. —— an increase on tariffs from 10—25% on $2 billion of chinese exports, due on january i, will be put on hold. the chinese have agreed to buy substantially more agricultural and industrial products from the us to reduce the trade deficit. talks on outstanding issues, like intellectual property theft, will get under way immediately. there was a lot of detail still missing from this agreement. when the chinese say they'll buy substantially more american goods, what does that mean? the devil is always in the detail in trade talks, but nevertheless, global markets will be relieved progress has been made, but this is a ceasefire, not the end of hostilities. there was another important agreement between the two men last night which might have

greased the trade deal. america's most unwanted import from china is the highly addictive and deadly drug, fentanyl. the opioid epidemic is killing tens of thousands of americans each year. president xi's offer to make it illegal in china was something that president donald trump has been long demanding. last night, he got what he wanted. this has been a slightly fraught, fractious g20, but with the chinese and americans pulling back from the brink, that is a limited success. jon sopel, bbc news, buenos aires. do stay with us on bbc news, still to come: an independent investigation at the fashion group ted baker, following claims its chief executive forced staff to let him hug them. it's quite clear that the worst victims of this disaster are the poor people living in the slums which have sprung up around the factory. i am feeling so helpless that the children are dying in front of me and i can't do anything. charles manson is the mystical

leader of the hippie cult suspected of killing sharon tate and at least six other people in los angeles. at 11am this morning, just half a metre of rock separated britain from continental europe. it took the drills just a few moments to cut through the final obstacle. then philippe cozette, a minerfrom calais, was shaking hands and exchanging flags with robert fagg, his opposite number from dover. this is bbc news. our main story this hour: the un warns the threat posed to all of us by climate change has never been this serious,

as a global climate summit opens with a push to cut emissions. well, let's stay with that story. mark howden is the director of the climate change institute at the australian national university in canberra. he also shared the nobel peace prize with the ipcc and al gore in 2007 for his contribution to climate change research. well, i spoke to him earlier about the tough negotiations that will take place at the copzii conference. it's a classic example of the challenge that the paris agreement has, in terms of being operationalised, in terms of making it a reality, where you have a country which has a heavy dependence on fossil fuel, so there's a lot of industry, a lot of governments which actually relate to that, and a lot of community support for that, and so changing that around is a classic case study of the things that we need to do. how do we have a just transition

from where we have been in terms of our energy sources to where we need to be to meet the paris agreement? given that this conference is about how to make the paris agreement a reality, isn't there a real issue that they may not be able to come up with a result at such a divided time? look, i think that it actually is a real challenge, so it's a very complex set of arrangements in terms of essentially establishing the rule book for the paris agreement — that's how we can actually put that into practice on the ground, but also how to build up the ambition for future emissions targets, so how do we increase emissions reductions that have already been agreed on in the paris agreement? and to do that, there's lots of different components and they are related to each other, so the elements in relation to say adaptation relate to what happens in terms of loss and damage, and what happens in loss and damage related to what happens in the finance systems.

and so, this is a set of negotiations with many moving parts and many different components, many of which aren't necessarily agreed across the different countries there. a lot of the focus has been on the united states withdrawing from the paris agreement. the us is a big polluter. are they a crucial part of this, or can the world change without them ? i think what we've already seen is many countries and groups of countries stepping up to the mark and saying that if the us is stepping out, we're going to step in. it's notjust the eu, it's notjust china that is doing that, but also many governments and businesses and communities and cities in the us are saying the same thing. if the federal government, the us government isn't going to step in and live up to the paris agreement commitments, they will. and so, so we're seeing very much a change in the geopolitics of power within our systems, but also happening at the domestic level. so we're seeing governments

and local governments and others stepping in and starting to take over where arguably, it's the national government should be acting best. talking about the domestic agenda, as you are in australia, i have to ask you about the australian government, which very much — the conservatives appear to almost deny climate change is happening, and australia is a very rich country. given we're seeing that on a particular level, doesn't that mean it's going to be really hard to get any sort of consensus? well, it's really interesting you raise that. so the vast majority of australians — over three quarters of australians — when surveyed, say they want more action on climate change, even if it costs them personally some money. so the vast majority of australians say yes, we want more action, but the politics has been really problematic and polarised for several years, and that's actually slowing down action on climate change. so recently, there was the un

emissions gap report, which actually assessed our policies and said those policies are not adequate to actually meet our national paris agreement commitments and, in fact, even the government's own projections say that we're going to fall short of our paris agreement commitments. there is a really interesting thing in australia where the gap between public opinion and public policy is growing and, at some stage, that gap will have to close. you can find more on the climate talks and general information about climate change on our website. articles include this explanation of the current state of global warming in seven charts. simply head to bbc.com/news. you can also download the news app. with nine days to go until the british prime minister's brexit deal is put to a parliamentary vote, uk members of the westminster parliament have been warned that a failure to support her could lead

to leaving without an agreement or no brexit at all. michael gove, who was one of the leaders of the leave campaign in 2016, said on sunday that while the deal was not perfect, voting it down could result in another referendum. the opposition labour party claimed it would push for a no confidence vote if theresa may loses on the 11th of december. our political correspondent ben wright reports. after meeting world leaders in argentina, theresa may returns to the harsh political realities of westminster, where she has nine days to sell her brexit deal to a deeply sceptical parliament. the area in which i have the greatest concern... ministers accept the agreement on the table is a compromise but today received a punchy sales pitch from a key brexit—supporting member of the cabinet. this deal, of course, is not perfect. but it does provide those of us who campaigned to leave with an opportunity to take back control of our borders and have

control of our immigration policy. it means we end the huge automatic sums that go to the eu every week, and it gives us the capacity in huge sectors of our economy to diverge, if we think that's right. one of the leading figures in the leave campaign, michael gove has stuck by the prime minister, refusing to follow other brexiteers out of the cabinet, and mr gove says tory mps who want to leave the eu have no choice but to vote for the deal. i reflected long and hard about this deal but i've concluded, like lots of people, that while it is imperfect, it is the right thing to do. but former allies in the brexit cause have split, and dozens of tory mps who hate the compromise deal remain determined to defeat it in the commons. it is hugely difficult, this is an important issue, it's a big step to vote against something that your government, your prime minister is advocating, and i don't really believe the sort of the fanciful

numbers about sort of 100 conservative mps voting against it. but there will be, you know, at least 40, i think, who have such grave reservations, we'lljust have to vote against it. the withdrawal deal contains a mechanism for guaranteeing no checks on the irish border after brexit. it would kick in if a trade deal between the uk and the eu can't be agreed in time. theresa may's critics worry the uk could be stuck in this arrangement indefinitely, and want to see the government's full legal advice. that will be the battle in the house of commons tomorrow, when the attorney—general makes a statement to mps. it will be the first skirmish in what will be a compelling and profoundly important few days in parliament, leading up to the big vote on december 11th. theresa may has very little time to persuade her mps in the commons to back her plan, and the question then, that nobody can answer, is what happens if her deal is rejected ? if she loses that vote, the legislation that we have already passed says she must come back

to the house and make a statement about what she's going to do next. now, technically, she's got 21 days to do that but she will probably come back the next day, so we need to see what that is, but it seems to me that if the prime minister has lost a vote of that sort of significance, then there has to be a question of confidence in the government. and labour hopes that might lead to a general election. some tory mps will urge the government to leave the eu with no deal, but pressure will continue to build for the whole issue to be put back to voters. that's a choice parliament's clearly struggling to come to terms with and can't agree on, so i think it's the best thing now, given we had a referendum in the first place, let's go back to the public — they can give their informed consent on the way forward. last week, theresa may plugged her brexit plan on a tour of the country. but it's mps she needs to convince. her future, the country's future, will be decided during a critical winter in politics. ben wright, bbc news. the international fashion brand

ted baker has promised an independent investigation into allegations of what's described as "forced hugging" by its chief executive. ray kelvin is pictured here. he usually chooses to be photographed not showing his face. staff have begun an online petition accusing the 62—year—old founder of verbal, physical and sexual harassment — claims they say are entirely at odds with the company's values. our business correspondent joe miller has the details. an anonymous petition was posted online just a few days ago and it's already garnered around 2,000 signatures. and in it, employees at ted baker accused the company's boss, ray kelvin — who took it from glasgow selling shirts to a globalfashion phenomenon — not only engages employees in unwanted embraces but has also asked female workers to sit on his knee and whether they could massage their ears. they also say he engages in sexual

innuendo, and the creator of the petition says that when they went to hr to complain, they were told that "this is just what he is like." now, ted baker has issued a statement, saying that these allegations are not in line with the values of the company or the ceo, but they do say that hugging has become part of the culture at ted baker — even though they say it is always voluntary — and they say that the boss often greets people, whether they are shareholders or business partners, or indeed colleagues, with a hug. mexico's new president, andres manuel lopez obrador, is wasting no time in getting to work on his campaign pledge to see off so—called elitism in the country, starting with getting rid of his presidentialjet. mr lopez obrador‘s representatives say the aircraft, which cost $218 million, will be kept at an airfield in california while a buyer is sought.

the new president, who took office on saturday, said he will fly commercially in future. another 60 federally—owned planes and 70 helicopters are also expected to be auctioned off soon. police in new york say they have found a couple who lost an engagement ring down a drain, thanks to people sharing the story on twitter. the man had proposed to his girlfriend on friday night but shortly afterwards, they dropped the ring in times square. lebo diseko has the details. a moment to remember, but for the wrong reasons, as a couple lose their engagement ring down a grate in new york. they were walking through times square after the groom had popped the question earlier in the day, when the ring slipped off the bride—to—be's finger and down the grille. the couple searched for at least two hours, to no avail. they eventually gave up, thinking it was lost forever. enter new york's police. they opened up the covering and continued the search after the couple had gone.

when it had not been retrieved that evening, these officers came back the next day and found it. a very lucky break. it's like finding a needle in a haystack, you know, because we've been plenty of these searches where we have come up with nothing, unfortunately, and, you know, fortunately, this one has a good ending to it, so... the only problem was they did not have the couple's details and so the next challenge was to find them. the nypd put out a twitter call to action, asking new yorkers to help track the couple down. twitter worked its magic and the two were found. their names arejohn and daniella and they were told the good news by friends moments after landing back in the uk. they say they are overjoyed and have promised the police a special mention on their big day. lebo diseko, bbc news. and before we go, we'd like to leave you with these pictures —— and daniela de tweets that they

we re —— and daniela de tweets that they were proposed in central park and the ring the drain so she will probably get the ring resized now that she is getting it back. and before we go, we'd like to leave you with these pictures of an invasion of skiing and snowboarding sa ntas. it is already that time of year! they took to the slopes in the us state of maine. the event is staged every year to raise money for local charities. as you can see, most of the father and mother christmases proved to be quite handy on the snow, even without a reindeer or sleigh around to help. i'm sure they wanted some assistance though. it is time to go skiing! don't forget, and you can go to our website for more of our top stories. you can reach me on twitter — i'm @regedahmadbbc. see you soon. hello. more rain for parts of england

and wales in the day ahead. tuesday, quieterforall, but then the weather gets pretty busy again from wednesday, as we will see. a chilly start the further north you are as monday begins and in scotland, the risk of ice on untreated services because we had wet weather overnight clearing away, allowing temperatures to dip away. as we go on through the day, this is the area of cloud. showers and outbreaks of rain moving through england and wales, producing heavy bursts, squally winds, south wales and south—west england too. northernmost counties of northern england and northern ireland and much of scotland will stay dry and sunny. on the northerly breeze, quite chilly and further showers running into northern scotland. wintry in nature to relatively low ground as we go through the late afternoon evening, but a big range of temperatures, very mild across south wales and southern england, with temperatures approaching the mid—teens. on the northerly flow, that colder air filters southwards across all parts into monday night and tuesday morning. we noticed showers around scotland, wintry in nature and a dusting of snow possible and icy patches again, as tuesday begins. but it does look like a widespread

frost is going to be the most noticeable part of tuesday morning and there could be a few fog patches around as well. we know it is going to be cold as tuesday begins, but there will be plenty of sunshine around. temperatures will be held down into single figures, despite the sunshine, after that cold, frosty start and this looks to be the coldest day of the week, more widely speaking. then the weather is about to change once more. notice an area of cloud or rain pushing into the far south—west, while many stay dry during daylight hours, it seems rain approaching in cornwall and devon. this next weather system, the busy part of the week starts to take its wet weather northwards across part of england and wales into northern ireland through tuesday night into wednesday morning. it hasn't finished there either. still some uncertainty about the northern extent, but it could push into parts of scotland, we know there is a cold air in place, we could see snow on the hills out of that and still big a range of temperatures north to south across the uk, northern scotland

more likely to stay dry and avoid this weather system. there will be another one coming in from the atlantic as we go through thursday, the rain does not look particularly heavy and by the end of the week, a deepening area of low pressure system weather but also stronger wind, gales or severe gales in places as we go into friday. yes, looking pretty busy from wednesday onwards, but it is particularly on friday that there is a risk of seeing some disruptive winds. still chilly in the north, mild in the south. bye bye. this is bbc news. the headlines: the united nations climate chief has warned that global warming is posing a greater risk to humanity than ever before. she told an international conference on climate change that this year was going to be one of the four hottest on record. the frenchjustice minister has promised that the courts will be tough on people who resorted to violence in anti—government protests on saturday. the paris police chief said ball bearings and hammers were thrown at the security forces. nearly 400 people were arrested. donald trump and xijinping have agreed to put their trade
